IMPROVEMENT IN LIGHTING APPARATUS.

Speciicatlon forming part of Letters Patent N0. 204,639, dated June 4,1378; application filed May 16, 187e.

To all zrhom it may concern:

Be it known that I, CHARLES S. WELLS, of New Haven, county of New Haven,and State of Connecticut, have invented certain new and usefulImprovements in Lighting Apparatus, of which the following is aspeciiication:

Figure 1 is a plan View of a car made by a horizontal section near itstop, showing seats running lengthwise of the car, A and B being itsplatforms. Fig. 2 is a vertical section of the tube arranged on theoutside of the car, showing a light and reectors.

My invention relates to lighting the interior of cars by means of alight on the out-side of the same; and consists in the arrangement of atube or chamber on the outside of a car provided with a light andreliectors and of reflectorsV within the car for diffusing the lightthroughout the interior of the same.

In Fig. 1, C is a cylindrical pipe or chamber arranged on the outside ofa car near its roof or top, and extending beyond the body of the car, sothat its end may be reached from the platform. A side pipe, D, of equaldiameter, connects with and opens into the pipe C, making an acute anglewith it. The pipe C has an opening in its end near the platform, throughwhich the light dis reached. It is provided with the concave reflectorc, Fig. 2, and with a reiiector, a, which is indicated by broken linesin Fig. 1. This relector a is placed at such an angle with the pipe Cand beam of light coming from the light d and reflector c as to throwthe beam of light through the side pipe D onto the reflector e. The pipeC is also provided with the light d, Fig. 2, which may be any ordinarylight, but, preferably, a calcium-light, in which ease the cylindersholding the gases are arranged on the top of the car and are connectedby pipes with a burner, which throws its jet of flame onto lime arrangedin the position of the light d. The opening or chimney x allows theproducts of combustion to escape.

In Fig. 1, e is a reflector of any required form, which is placed on theinside of the car and arranged in line with the side pipe D.

The construction and arrangement of the elements may be varied without adeparture from my invention. For example, the pipe C may be extended asfar as the body of the car extends, and another side pipe, like D, beunited to it. If this form of construction is adopted the reflector a isaltered and made to extend only one-half the way across the pipe C, andanother reiiector is inserted near the end ot the pipe. Anotherreflector is also arranged within the car, corresponding to thereflector e.

The elements of my apparatus being thus constructed and arranged, thelight from the light d and reflector c is reflected by the reiieotor aonto the reflector e, which diifuses it throughout the interior of thecar, the intensity of the light within the car Varying with theintensity of the light d.

Having described my lighting apparatus, what I claim as new, and desireto secure by Letters Patent, is-

The pipe C, arranged on the outside of a car, and provided with the sidepipe D, reilectors a and c, and light d, in combination with thereflector e, arranged within the car and in line with the side pipe D,as shown and set forth.
